Item A case report of granuloma faciale, an uncommon cutaneous vasculitis(2019) Arellano, Javier; Vargas, Pablo; Pulgar, Constanza; Neely, Gabriel; Corredoira, YamileGranuloma faciale is an uncommon benign dermatosis, with unknown etiology, usually asymptomatic, characterized by chronic inflammation localized in sun-exposed areas of the face with a characteristic histological pattern. Although response to treatment is variable, there are multiple therapeutic alternatives that have been reported to be effective in some patients, including systemic treatments with steroids and dapsone or also topical treatments like intralesional corticosteroid, cryotherapy and calcineurin inhibitors, such as tacrolimus. We present the case of an adult patient with an asymptomatic erythematous-violet plaque on the right cheek, with progressive slow growth over two years, clinically and histologically and pathologically compatible with a facial granuloma. The patient responded well to intralesional corticosteroids.Item Primer reporte de caso autóctono de tinea nigra en Chile(2019) Arellano, Javier; Vargas, Pablo; Urrutia, MauricioTinea nigra is an infrequent superficial mycosis caused by the dematiaceous fungus Hortaea werneckii. It usually occurs in tropical coastal areas, with very few reports in South American countries with temperate climates, generally corresponding to infections imported by travelers. We present the case of a Chilean adult patient, with no previous history of recent trips, with clinical and microbiological background consistent with palmar tinea nigra, treated with oral itraconazole and topical sertaconazole with a favorable response. This article is the first case reported in Chile, of autochthonous origin.
